Ni ukubera iki Ubushyuhe bwo hejuru Nylon bukundwa gukoreshwa muri moteri yimodoka ya Periferique?

Bitewe na plastike yibikoresho bya elegitoroniki, moteri, nibice byimodoka, ibisabwa birenze bishyirwa kumikorere ya nylon no kurwanya ubushyuhe bwinshi. Ibi byafunguye intangiriro yubushakashatsi niterambere no gukoresha ubushyuhe bwo hejuru bwa nylon.

Ikirahure kinini cyikirahure cyongerewe ubushyuhe bwo hejuru nylon PPA nimwe mubwoko bushya bwashimishije abantu benshi, kandi ni kimwe mubikoresho byihuta cyane kandi bikoresha amafaranga menshi. Ikirahuri cya fibre cyashimangiye ubushyuhe bwo hejuru nylon igizwe nibikoresho bishingiye ku bushyuhe bwo hejuru nylon PPA biroroshye gukora neza cyane, birwanya ubushyuhe bwinshi nibicuruzwa bikomeye. Cyane cyane kubikoresho bya moteri yimodoka ya periferique, ikeneye guhangana nibisabwa bikabije byo gusaza, nylon yubushyuhe bwo hejuru yahindutse buhoro buhoro amahitamo meza kubikoresho bya moteri yimodoka. Nikiidasanzwehafi yubushyuhe bwo hejuru nylon?

1, Imbaraga zidasanzwe za mashini

Ugereranije na nylon gakondo ya alifatique (PA6 / PA66), ubushyuhe bwo hejuru nylon bufite ibyiza bigaragara, bigaragarira cyane cyane muburyo bwibanze bwibicuruzwa nibirwanya ubushyuhe. Ugereranije nimbaraga zibanze zubukanishi, ubushyuhe bwo hejuru nylon ifite ibirahuri bimwe byikirahure. Irenze 20% kurenza alifatique nylon gakondo, ishobora gutanga ibisubizo byoroheje kubinyabiziga.

Inzu yimodoka ya termostatike ikozwe mubushyuhe bwo hejuru nylon.

2, Ultra-hejuru yubushyuhe bwo gusaza imikorere

Hashingiwe ku bushyuhe bw’ubushyuhe bwa 1.82MPa, ubushyuhe bwo hejuru nylon 30% fibre yibirahure byongerewe imbaraga birashobora kugera kuri 280 ° C, mugihe gakondo ya alifatique PA66 30% GF igera kuri 255 ° C. Iyo ibicuruzwa bisabwa byiyongereye kugera kuri 200 ° C, biragoye ko nylon gakondo ya alifatique yujuje ibisabwa kubicuruzwa, cyane cyane ibicuruzwa bya moteri bya moteri byabaye mubushyuhe bwinshi nubushyuhe bwo hejuru mugihe kirekire. Mubidukikije bitose, kandi bigomba kwihanganira kwangirika kwamavuta yubukanishi.

3, Ihame ryiza cyane

Igipimo cyo gufata amazi ya alifatique nylon kiri hejuru cyane, kandi igipimo cyuzuye cyamazi gishobora kugera kuri 5%, bigatuma ibicuruzwa bitangirika cyane mubicuruzwa, bidakwiriye cyane kubicuruzwa bimwe na bimwe bihanitse. Umubare wamatsinda ya amide mubushyuhe bwo hejuru nylon uragabanuka, igipimo cyo kwinjiza amazi nacyo ni kimwe cya kabiri cyibisanzwe bya alifatique nylon, kandi guhagarara neza ni byiza.

4, Kurwanya imiti nziza cyane

Kubera ko ibicuruzwa biva muri moteri yimodoka bikunze guhura nibikoresho bya chimique, hasabwa byinshi murwego rwo kurwanya imiti yibikoresho, cyane cyane kwangirika kwa lisansi, firigo hamwe nindi miti bigira ingaruka mbi kuri polyamide ya alifatique, mugihe ubushyuhe bwinshi Imiti idasanzwe imiterere ya nylon igizwe nibi bitagenda neza, kuburyo isura yubushyuhe bwo hejuru nylon yazamuye ikoreshwa rya moteri kurwego rushya.

Imodoka ya silinderi yimitwe ikozwe mubushyuhe bwo hejuru nylon.

Inganda zikoresha amamodoka

Kubera ko PPA ishobora gutanga ubushyuhe bwo kugoreka ubushyuhe burenga 270 ° C, ni plastiki nziza yubuhanga kubice bitarwanya ubushyuhe mu nganda z’imodoka, ubukanishi, n’ikoranabuhanga / amashanyarazi. Muri icyo gihe, PPA nayo nibyiza kubice bigomba gukomeza ubusugire bwimiterere mugihe gito cy'ubushyuhe bwo hejuru.

Automotive hood ikozwe mubushyuhe bwo hejuru nylon

Muri icyo gihe, plastike yibice byibyuma nka sisitemu ya lisansi, sisitemu yo kuzimya, hamwe na sisitemu yo gukonjesha hafi ya moteri yasimbujwe ibyuma bisusurutsa kugirango bikoreshwe, kandi ibisabwa kubikoresho birakomeye. Kurwanya ubushyuhe, kuramba, hamwe nubushakashatsi bwimiti ya plastiki yabanjirije-intego rusange yubuhanga ntishobora kongera ibyangombwa.

Byongeye kandi, ubushyuhe bwo hejuru bwa nylon bukomeza ibyiza bizwi bya plastiki, aribyo koroshya gutunganya, gutema, koroshya igishushanyo mbonera cyibice bigoye bikora, hamwe no kugabanya uburemere n urusaku no kurwanya ruswa.

Kubera ko ubushyuhe bwo hejuru nylon bushobora kwihanganira imbaraga nyinshi, ubushyuhe bwo hejuru nibindi bidukikije bikaze, birakwiriye cyane euduce twa ngine (nkibifuniko bya moteri, guhinduranya no guhuza) hamwe na sisitemu yo kohereza (nko gutwara amakarito), sisitemu yo mu kirere (nka sisitemu yo kugenzura ikirere) hamwe nibikoresho byo gufata ikirere.

Ibyo aribyo byose, ibintu byiza byubushyuhe bwo hejuru nylon birashobora kuzana inyungu nyinshi kubakoresha, kandi mugihe uhinduye ibikoresho bya PA6, PA66 cyangwa PET / PBT kuri PPA, mubyukuri ntabwo bikenewe guhindura ibishushanyo, nibindi, birakwiye rero kubisabwa bitandukanye bisaba kurwanya ubushyuhe bwinshi. Hariho ibyerekezo byinshi.
